I generated a proxy class given a URL to a WSDL.
I need to let the end-user change the service's URL to his specific URL, like this:
ServiceProxy.Url = [URL set by end-user];
The issue is that this URL should not point to the WSDL, it should be the binding address which is found within the WSDL (wsdl:service -> wsdl:port -> wsdl:address) (this is a SAP web service, I understand that is why I must use the binding address).
I am thinking of using the XDocument class to get that value, but I am wondering if there is any "built-in" functionality in WCF or web services to get the binding address. Thank you.
I did a small function in VB.NET (sorry!) based on code at Parse Complex WSDL Parameter Information . Hope it helps.
Public Function GetURLFromWSDL(ByVal wsdl As String) As String
Dim request As HttpWebRequest = WebRequest.Create(wsdl)
request.ContentType = "text/xml;charset=""utf-8"""
request.Method = "GET"
request.Accept = "text/xml"
Using response As WebResponse = request.GetResponse()
Using stream As Stream = response.GetResponseStream()
Dim service As ServiceDescription = ServiceDescription.Read(stream)
Dim binding As SoapAddressBinding = service.Services(0).Ports(0).Extensions(0)
Return binding.Location
End Using
End Using
End Function

I'm trying to implement Basic Authorization for an ASMXweb service. I created the client as a service reference in VS2015. I'm using code in Asmx web service basic authentication as an example.
I'm entering login info in ClientCredentials as below
Dim svc As New WebServiceSoapClient()
svc.ClientCredentials.UserName.UserName = "userId"
svc.ClientCredentials.UserName.Password = "i2awTieS0mdO"
My problem is that in the Authorization HttpModule in the web service, these credentials are not being passed to module. Is there an alternate way to do this?
I found the parts answer at How to add HTTP Header to SOAP Client. I had to combine a couple of answers on that page to get it to work.
Dim svc As New WebServiceSoapClient()
Dim responseService As SoapResponseObject
Using (new OperationContextScope(svc.InnerChannel))
Dim auth = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("userId:i2awTieS0mdO"))
Dim requestMessage = New HttpRequestMessageProperty()
requestMessage.Headers("Authorization") = auth
OperationContext.Current.OutgoingMessageProperties(HttpRequestMessageProperty.Name) = requestMessage
dim aMessageHeader = MessageHeader.CreateHeader("Authorization", "http://tempuri.org", auth)
OperationContext.Current.OutgoingMessageHeaders.Add(aMessageHeader)
responseService = svc.ListDistricts(requestService)
End Using
One key thing to be aware of is that the soap client call has to be inside the Using statement. In the above code, this is the next to last line.
I'm developing an intranet (WRITTEN IN C#) which is going to gather all software applications used in my company. Some of these applications are not internal (so I can't actually see nor manage the source code).
I have to "bypass" a login page of an external application (WRITTEN IN PHP), sending username and password from asp.net (my intranet).
I don't really know HOW to manage this, IF possibile..
I only know that it's expecting a $_POST["l_username"] and a $_POST["l_passowrd"].
I've been looking for a solution for hours now..and still..nothing seems to be working. I read maaany post but there are not useful in my case.
EDIT 1:
public void sendInfo(string url, string data)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
string Data = data;
byte[] postBytes = Encoding.ASCII.GetBytes(Data);
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = postBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
Stream resStream = response.GetResponseStream();
var sr = new StreamReader(response.GetResponseStream());
string responseText = sr.ReadToEnd();
req.AllowAutoRedirect = true;
}
This is the code I've been trying to use when I click on the link (I'm using a LinkButton)..but it is not redirecting me to the page. It's supposed to redirect, logging in using the parameters I give in Data and show me the main page of the external application..any suggestions would be greatly appreciated!
EDIT 2:
I found a code which seems to be working, finally!
You can find it ->HERE<-.
I tried it using a simple Web Form (with a LinkButton) and a class, it works perfectly.
My problem now is that my intranet uses a MasterPage, and when I'm calling the method from a Content Page..nothing happens.
What can I do to have this code working on a Content Page?
You can specify the POST method for WebRequest (more details in this SO answer: curl Request with ASP.NET )
You should build a Request with the ASP.net WebRequest. You know which data to send, so that shouldn't be a problem!
At the end I used this ->code here<- and it worked just fine.
Couldn't understand why it won't work using master and content pages, but I managed without them.
Set xml = Server.CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", "http://www.indexguy.com/request_server.cfm?member_id=15893&id="+request.querystring("id")+"&"+request.querystring, False
xml.Send
How can I build the querystring parameter to a string object in C#/VB.NET
"member_id=15893&id="+request.querystring("id")+"&"+request.querystring"
If you are looking to build a querystring, String.Format("{0}", arg) might be a cleaner method to construct it.
For ASP.NET, you're going to want to replace the Server.CreateObject("Microsoft.XMLHTTP") with HttpWebRequest.
As for building the query string, that's still identical. You can still retrieve query string parameters by indexing into Request.QueryString. If you're using C# you can keep the + for string concatenation but might be more acceptable to use & in VB.
In ASP.NET the Page class exposes a Request property which provides access to a QueryString property - this is a NameValueCollection that lets you get values out in much the same way as in your existing example, by specifying keys:
var id = Page.Request.QueryString("id");
var newQuery = string.Format("?member_id=15893&id={0}&", id);
The above can easily be expanded to build more into your required query string.
As for the request you're initiating, that can be achieved using a WebRequest instance; to alter the sample from MSDN only slightly, here is an example:
WebRequest request = WebRequest.Create(yourUrl + newQuery);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Response.Write(response.StatusDescription);
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader (dataStream);
string responseFromServer = reader.ReadToEnd();
Response.Write(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
I have a web service, which accepts XML input. What I am trying to do is setup an aspx page which posts xml to the service. Here is my code so far, but I am getting an error 400 (bad request) when I try to submit...

Protected Sub Submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit.Click
Dim strDataToPost As String
Dim myWebRequest As WebRequest
Dim myRequestStream As Stream
Dim myStreamWriter As StreamWriter
Dim myWebResponse As WebResponse
Dim myResponseStream As Stream
Dim myStreamReader As StreamReader
' Create a new WebRequest which targets the web service method
myWebRequest = WebRequest.Create("http://foo/p09SoapHttpPort")
' Data to send
strDataToPost = DataToSend.Text & Server.UrlEncode(Now())
' Set the method and content type
With myWebRequest
.Method = "POST"
.ContentType = "text/xml"
.Timeout = -1
.ContentLength = strDataToPost.Length()
End With
' write our data to the Stream using the StreamWriter.
myRequestStream = myWebRequest.GetRequestStream()
myStreamWriter = New StreamWriter(myRequestStream)
myStreamWriter.Write(strDataToPost)
myStreamWriter.Flush()
myStreamWriter.Close()
myRequestStream.Close()
' Get the response from the remote server.
myWebResponse = myWebRequest.GetResponse()
' Get the server's response status
myResponseStream = myWebResponse.GetResponseStream()
myStreamReader = New StreamReader(myResponseStream)
ResponseLabel.Text = myStreamReader.ReadToEnd()
myStreamReader.Close()
myResponseStream.Close()
' Close the WebResponse
myWebResponse.Close()
End Sub
End Class
If anyone knows of any good web resources on how to upload .xml files to a web service method that would also be a great help and would answer this question as I can re-work it that way.
Thanks.
P.S in the last edit, I modified the code to have .contentlength (thanks for the assistance). Unfortunately after this I am still getting 'Bad Request'. If anyone can confirm / disconfirm my code should be working, I will start investigating the service itself.
The data you're trying to post might look a little funny if you're concatenating a time string to it:
strDataToPost = DataToSend.Text & Server.UrlEncode(Now())
If DataToSend is proper XML, then you're adding the Url Encoding of Now() which makes me think it will no longer be valid XML.
Check to make sure your StreamWriter is not inserting additional characters (CR, LF). If it does, then the length you're sending does not correspond to the actual data, but that probably wouldn't have caused a problem before you started sending the content length.
Is your web service configuration to accept XML directly? I'm wondering if you might have to encapsulate the XML in multipart/form-data in order for your web service to accept it.
I'm not a web service expert, but I compared your code to some working code I have, and the only relevant difference is that you are not setting the ContentLength of your request.
myWebRequest.ContentLength = strDataToPost.Length()
I'm trying to send an HTTP command using VB.NET and I'm not quite sure how to do it. I don't want to actually navigate to the page, just execute the command.
http://xbmc.local/xbmcCmds/xbmcHttp?command=ExecBuiltIn¶meter=XBMC.updatelibrary%28video%29
What I'm doing is building an integrated interface for my XBMC home theater, and my home automation.
You can use the WebRequest object to send an HTTP Request.
' Create a WebRequest object with the specified url. '
Dim myWebRequest As WebRequest = WebRequest.Create(url)
' Send the WebRequest and wait for response. '
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
The WebResponse class has a number of properties you can check to see if the request succeeded or not. And just something to be aware of, GetResponse() will throw an exception if it times out.
Try the following
Dim client = WebRequest.Create("http://xbmc.local/xbmcCmds/xbmcHttp?command=ExecBuiltIn¶meter=XBMC.updatelibrary%28video%29")
Dim response = client.GetResponse()
